. Letters .Patent No. 98,734, dated January 11, 1870.

IMPROVEMNT IN .iEORCE-PMPS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that Awe, WILLIAM BEERs and WIL- MAM RAYNOR, of Milan, in the county of Erie, and State of Ohio, have invented a new and valuable Improvement in Double-Acting Force-Pumps; and we do hereby declare that the followingis a full, clear, and exact description of the construction and operation ofthe same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawings is a side view of our invention.

Figure 2 is a central vertical section of the same.`

Figure 3 is a representation of the inner surface of one of the plungers. v

Our invention relates to force-pumps, and consists, mainly, in the construction and novel arrangement of devices, whereby a pump of this class is enabled to work in the shallowest water.

The letter A, of the drawings, designates the body of the pump, formed o f wood or suitable metal, through which the water from the piston-cylinder B is forced, passing out at the spout a. i

To the lower part of this conduit A is firmly secured the cylinder' B, by the bolts and nuts z z and clamps z 'z' lhe cylinder B is formed in two sections, bolted together longitudinally by screws or bolts, as shown at c c', and the joints suitably packed.

To the outer section of cylinder B, or ther section farthest from the conduit A, is fastened by screws,-

the conduit C, through ,which the water enters the pump. Both the cylinder B and conduit C, are generally made of metal. r

The cylinderB is open at each eind, and divided centrally by the disk' b of iron, whose edge fits into ay groove, q, formed in the wall of the cylinder, and snitably packed. Above this disk two openings are formed,

through which -the cylinder communicates, on one side with the conduit A, and on the other side with the conduit O.

To these openings are fitted the valves c and c, respectively arranged to admit water into the cylinder B from the conduit C, and to allow of its passa-ge from the'cylinder into the conduit A, but preventing a reverse movement.

Below the disk `b, two similar valve-openings, O and A', are formed, establishing a like commuuication'bej tween the cylinder B and the conduits A and O.

D D designate the plnngel's or piston-heads, attached, one to each end of the piston-rod d, which passes through a nicely-tting opening in the centre of the fixed disk b.

Each piston-head D `is grooved around the edge deeply, and the groove packed with rubber packing t..

Four small openings, i, are made through the inner wall of each groove, forming a communication between the base of the groove and the cavity of the cylinder,

in such a manner that a pressure on the Water in the cavity of the cylinder will force it through these openings into the groove behind `the rubber packing, thus' causing it to fit more closely the wall of the cylinder.

Tot-he staple n, fastened above the Vupper pistonhead, tothe end of the piston-rod, is pivoted the lower end of the pitman e, whose upper end -is pivoted to the crank G, whose shaft, g, passes through the4 upper part ofthe body A of the' pump, and isa turned by4 means of the hand-crank K. Y Y

The springs s s are employed to assistin the closing of the valves a and A', which are usually fastened at the lower sides of the openings in suoli a manner that they will open upward.

It is apparent, that if this pump be placed upright in water of suicient depth to immerse the mouth orlower end ofthe conduit 0,' and the piston worked by turning the hand-crank K, as the plungers D D ascend, valves a and O will be closed, valve c will be opened, `and water will rush in to fill the partial vacuum formed above the disk b, while the valve A' will be opened by the pressureof the water as it is forced ont of the compartment below the disk b by compression. In like .ma-nner, as the plungers D D descend,

`the valves A and 'c will be closed, water will enter the lower compartment of the cylinder B through valve y O', and will be forced out through valve a by compression in the upper compartment.

When, as incase of a bored well, it is 'not convenient to introduce the-pump-stock and cylinder, a pipe maybe attached to the month ot' the conduit C, and'V communication thus established between the pump and the water. It will thus actas a suction-pump.

Vhat we claim as our invention, and desire -to sevcure by Letters Patent, isy The force-pump, herein described, having stock A,

cylinder B, open at bot-h ends, descending conduit C, dividingdisk b, 'grooved plungers I) I), with openings i t', and expansible packing t t, valves a c A C', when arranged as specified.

In testimony that we claim the abovehwe `have Ahereunto subscribed our names, in the presen-ce of two witnesses.

WILLIAM BEERS. VILLIAM RAYQNOR.'
